Vanderbilt game canceled on Hard rock

I had vandy -27.5 (bought down) as part of a parlay. When I went to bed that game amd parlay were both considered a loss since they won 28-9. I woke up and my balance is bigger than it should have been. I open up my finished bets....its now a win and that game voided.  Anyone know why?

The game ended early as a result of the coaches agreeing. There was lightning and a little over 2 minutes left.   Therefore I guess it wouldn’t be fair to give someone on the short side of a wager a loss in that situation.

 Fair. I supposena Google search would have answered that for me. I saw in the box score there appeared.to be 4 quarters played. Hence my confusion. Thanks for the info

Think 58 minutes have to be played for a game to be official. I could be wrong
